TminennvIcE Our invention -relates to amefchanical timing device intended, for general use 'butgespe- V cially adapted for use in-c0nnectienwvith aj concrete mixingmachinefer timing the mixa 6 ing; Ofia E'b'at'eh efeoneretei- It is a well known fact; in enginee'ringlthat the strength o'fedncreteidepends a great idea-l on the proper mixing of the ingredients, andthat all batches inza given job sho'u ldj-b'e alike in order to; secure uniform strength, and time required in making a mixture of a given strength is also well known. There is a tendency, "how'- ever, on thef part of contractors to s'light',the propertiming of the'mixing of c onerete in By theluse ofonr' invention, a b'atch'of 0on eret'e will be mixed a predetermined length n of time, in accordance with specifications, and

then automatically dumped. jAs the mechan-- ical" timer c'annot' betainpered (With, all
